Bug#1071518: paraview: s390x test failure: vtkClientServerStream::Invoke stream_value invalid

[Drew Parsons]

Package: paraview
Version: 6.0.1+dfsg1-5
Followup-For: Bug #1071518
X-Debbugs-Cc: debian-s390 at lists.debian.org
User: debian-s390 at lists.debian.org
Usertags: s390x

Internal tests (pvbatch -m paraview.tests) also fail with the same
error on s390x.

So skip debian/tests/paraview-batch on s390x

(presumably other bigendian systems are affected too,
like ppc64 or sparc64, but debci isn't run on them)
